A2 A4 Double Threaded Custom Fasteners M22 Hanger Bolt For Solar Panel

1.Product Description

hanger bolt joint can reach a high strength, that is, the strength of the stud welded joint is greater than the strength of the stud itself.How to install the double head bolt good economy for other welding methods, the advantage lies in the welding power.For mass produced workpieces, standard studs are low cost.Equipment and welding gun have a variety of types, equipment purchase cost is relatively low.According to the product, can be made into multi-station automatic welding machine, or high precision gantry CNC automatic welding machine.Stud welding has higher quality reproduction rate and lower reject rate.However, in the application of stud welding, it should be noted that the carbon content of steel is limited. For structural steel studs, they should be welded according to the recommended combination weldability of stud material and base material, otherwise there will be non-fusibility between the studs and the base material.The stud material and base material combinations outside the recommended range shall be tested to determine the weldability and the possibility of relevant inspection evaluation required by the product design of the anchor bolt.
